Texan barrels and bottles?

What twist are you using, Nick?....

I am using the TJ 1:26.  That barrel is very accurate.  I added a picture of the end of my Texan, you can see the barrel does not even go past the end of my barrel bushing I made to accept my 2 inch diameter silencer.

I measured the top hat, the 45 is larger diameter of the smaller part of top hat and the same on the outer diameter of the larger portion.  Hope that makes sense

Nick, is that "just" a end cap?  or does it somehow connect to a 1 piece barrel bushing?

So Doug, my lathe mentor, taught me how to make these.  That is a threaded endcap with a tight fitting barrel bushing.  It fits tight into the frame of the Texan and the barrel fits tight inside the bushing.  Then I screw the silencer onto that bushing.  Doug makes his similar but adds a lot of moderator but his guns are bench guns.  This is a hunting gun.  The silencer I have on it now is too long and I need to cut down the can so it is half the length but I had this one from a previous experiment and using it for now.

Still playing with this gun but I added a pic of a 100 yard group with 120 grain swage slug I make that was shot a few days ago.

You will get tank dump. A barrel with a smaller hole leaves a big lip that the air sees. Same reason you can't put a .177 in a .25 condor without changing out the valve return spring to a super stiff one.

Guess I'm barking up a tree that has been climbed before.

I'll admit I assumed the smaller projectile would lower the valve dwell not increase it.

I really like that endcap bushing idea.

That keeps the barrel straight in the frame.

This is what you do when your barrel is the bushing.
